Dolphins seem to be all over the news these day . Just last week we told you abouta pod of sperm cell hulk who adopt a misshapen bottlenose dolphin , and howa dolphin tangled up on a sportfishing hook asked a deep sea underwater diver for help . Now , grant to a study bring out in the diary Marine Mammal Science , a chemical group of dolphins were seen render to keep an ailing companion from drown by teaming up and propping it up to the surface with their trunk . It ’s the first time this form of conduct has ever been document in mahimahi .

Just as a word of advice , the picture above is quite sad , as it does show a dying , overwhelm dolphin who eventually succumbs to the elements . You may require to forfend the TV if you ’re particularly tender to this sort of stuff .
There are many documented account of dolphins come to the rescue of mankind , so it really should n’t be a surprise to find out that they also ferment to help each other out during a crisis situation . And indeed , since the 1960s shipboard soldier biologists have love about tutelage - gift behavior of dolphins , but only so - call ‘ nurturance behavior ’ when a mother tries to facilitate a stillborn calf to the airfoil by using her back .
But in this unprecedented face , a group of Korean research worker observe the dolphins lead a saving endeavor on a dying adult phallus . They did so while surveying a large radical of long - beaked common dolphins off the South Korean coast back in 2008 . Kyum J. Park of the Cetacean Research Institute in Ulsan , Korea and colleagues were observing a group of C of dolphinfish when they noticed that a small group of 12 had part from the large pod and were plash near the boat .
On closer review , the maritime biologists noticed that a distaff member of the pod was not doing so well . It had flushed scrape on its belly , and its flippers appeared to be paralyzed — an indicant of a severe and life - threatening injury . It was splosh its tail end , its consistence constantly tip over to one side , leaving its abdomen often visible to the research worker .
To foreclose it from drowning , the group of dolphinfish ingest play to support it from below , prod it and even out its equalizer . But after 30 minutes of this , they had to recur to more desperate standard : They formed a kind of raft by joining their bodies together . The biologists observed that five dolphins shape at a time , run along up horizontally so that the trouble dolphin could rally on their backs . The dolphins also used their beaks to keep the dying mahimahi ’s head up .
But the rescue attack was not to be . After a few minutes of this despair mensuration , the ailing dolphin died , its body hanging vertically in the water . Several dolphins continue to interact with the corpse , frequently rubbing and touching it , swim underneath , and blowing bubble on it . Eventually , however , it sank to the bottom , and they move on .
Now , as Michael Marshall of New Scientist is eager topoint out , “ The act does not needfully mean dolphin are selfless or can empathise with the pain of their kin group . ” He quote biologist Karen McComb who suggest that the simple-minded act of working together could bond the chemical group more powerfully , or that the effort could help asseverate the grouping , and thus better control their territory .
That ’s all fine and well , and even plausible . But scientists should n’t dismiss the theory that dolphins are truly empathetic and move out of a sense of compassion . In fact , cetaceans are one of only a few species , like humans , who possess mirror neurons — a cognitive dimension that endows beast with the power to forge a mental conception of another judgment , a biological requirement for compassion . And in fact , transmissible studies are show thatdolphins have a brain that ’s remarkably human - like in its capacities .

At any rate , more enquiry need to be done to prove that mahimahi have the capacity for empathy . But if their actions are of any indication , it may be a fault for us to withhold judgement on the matter .
